thanks mcgra i'll give them a call.all the other posts must have read it wrong, i did'nt ask if they worked or not.

to much rust behind the pads move them to other rust free areas & they should work fine until the rust reaches them again !
good luck

Hows it going Mark,

Was going to ask you to explain Capacitive rust protection , but I Googled it and got this from the CouplerTec site , isnt this the same as a sacraficial anode type set up exept the box supplies the electrons ?

Basically, rust is the loss of electrons from within the metal. Oxygen combines with the metal atom and forms FE2o3 Ferric Oxide, that?s rust.

Here we explain Capacitive Coupling in Laymen's Terms.

What we are doing is interfering with the oxidization cycle, in other words, tricking nature.

We achieve this by artificially pumping electrons into the vehicle so our supply of electrons exceeds the demand.

This is achieved by creating a capacitor, our pad that is affixed to the paint acts as the positive plate in the capacitor, the paint becomes the dielectric which in turn holds the charge static (keeps the electrons from flowing away) and the body of the vehicle or structure acts as the negative plate in the capacitor.

So what we are left with is a big capacitor;

- 1. The pad is the positive plate
- 2. The paint is the dielectric
- 3. The body is the negative plate

Electrons are built between the positive plate and the negative plate and the paint keeps them there. How Simple!
